About this app
CCAS (pronounced /ciːkæs/; CEE-kas) is an aircraft collision avoidance system, especially used by VFR pilots. CCAS operates in lower airspaces, depending on the terrain, from ground level up to 5,000 ft above ground level (AGL).
- Safety Without Barriers -
We firmly believe that safety in general aviation should not be a question of cost. The CCAS network is entirely free of charge, funded by donations, and designed to be universally accessible. With a focus on functionality over "bling," it ensures that pilots of recreational aircraft can benefit from a reliable interoperable network for collision alerts. Our mission is simple: "see, BE SEEN, and avoid."
- How it works -
Each CCAS client periodically sends its own position to the CCAS network. On the other hand, the CCAS servers broadcast all relevant traffic around this position back to the CCAS client. By using standard TCP connections combined with a highly optimized protocol, this operates almost in real-time.
Besides other CCAS users, the server also broadcasts traffic information from different other sources, such as ADS-B, as well as OGN/FLARM, to ensure maximum traffic awareness.
You can easily connect CCAS to your navigation app (e.g. SkyDemon, Foreflight, VFRnav, ...). This means that traffic is displayed directly on the moving map. Traffic data is transmitted via GDL90. In addition, CCAS can be used as a proxy for other traffic data sources such as Stratux, FLARM or ADS-B receivers.
- How to use -
In order to use CCAS and help increase safety in the air, just download the official CCAS client app. It's completely free by the way!
Important note on privacy: No registration is necessary. Upon the first launch of the client, a random ID is generated on the device. Each position message is encrypted and shared only with other CCAS users in immediate proximity. No flight history is saved.
- How to contribute -
Simply use the client. Every pilot using CCAS makes an important contribution to make the airspace safe.
